The implant body used was a titanium unit measuring 3.0 × 8.0mm. CA was synthesized as described by Doi et al. CA powder and granulated sugar adjusted to diameters of 250‒500 μm were mixed at a ratio of 1:1, placed in a metal die to form a cylindrical shape, and processed at a hydrostatic pressure of 200 MPa. The resulting cylindrical CA porous substance was immersed in distilled water for one hour to elute the sugar. After the substance was dried, the temperature was increased to 700℃ and the substance was left at that temperature for one hour to produce a sintered CA porous substance. The porous substance was then fragmented and run through a sieve to obtain CA porous substances with pore sizes measuring 600‒1,000μm. bFGF (Fiblast Spray®, Kaken Pharmaceutical Co., Ltd.) was used by dissolving 250μg in 1ml of normal saline. The bFGF-CA complex was used by impregnating 1ml of bFGF into CA. Three male beagle dogs were used in the study, with the experiment site being the bilateral mandibular third and fourth premolars. Under general anesthesia, an incision was made in the gingival sulcus of the third and fourth premolars. After the gingival sulcus was peeled away, the molars were split and extracted, and the incision was closed. Twelve weeks post-extraction, a full-thickness flap was peeled back from the third and fourth premolars under general anesthesia, and an implant fossa was created. A bone defect measuring 3.0mm across and 7.0mm high was created on the buccal side of the implant fossa, after which the implant body was placed. Eight weeks after surgery, the dogs were sacrificed and specimens were extracted and fixed in 4% perfluoroalkoxy alkane. The bone mineral content was measured using microcomputed tomography, resin sections were created, and histological evaluation was carried out. Measurements were also taken of the amount of new bone, the height of the new bone, and the rate of residual CA. Remnant CA granules were observed, but obvious bone augmentation was seen in the fibroblast growth factor (FGF) + CA group. It is possible that this was because CA assured space for new bone growth and bFGF promoted this growth. Moreover, in the FGF + CA group, the rate of residual CA was significantly lower than that in the CA group. It is possible that bFGF promotes the absorption of CA and the substitution of CA for bone.", "subitem_description_type": "Other"}]}, "item_10002_full_name_75": {"attribute_name": "著者別名",
